Receprocity break down in film vs. CCD/other

Robt

Once I laid on my stomach and took a shot that wasn't what I thought I was taking. I was a simple pix of a farm house while it was snowing, It shifted to a washed pastel shot that may be the best I've ever done. A pure accident.

What happened was the shot was the shot was a 1 or maybe 2 sec. shot on Kodachrome [ I think 2] ASA 25, I later figured out that I had discovered reciprocity breakdown.

What my question to you is how does the use of reciprocity break down apply to CCD or CMOS detectors? Do longer exposures cause marginally predictable shifts in digital as they do with films? My guess is the answer has more to do with noise than any other similarity.

Any response will be appreciated.

About the only change I have seen with long exposure compared to short exposure is a penchant for increased noise. But this tends to be more a factor of ambient temperature than anything else. The colder it is the less noise will accumulate.
